The Department's guidance for developing and conducting prize challenges pursuant to the America COMPETES Reauthorization Act of 2010 was issued on April 3rd, 2015. However, that Act was amended by Section 401 of the American Innovation and Competitiveness Act (AICA), signed into law on January 7th, 2017. Section 401 of this Act, known as the Science Prize Competition Act, among other things, simplified the process of offering and conducting prize competitions. Accordingly, the existing guidance (available for the record) is being modified to conform with the provisions of the ACIA. A list of on-going and completed prize challenges offered by federal agencies is available at challenge.gov. DOI guidance requires all challenges to be posted at that site as soon as possible, and it is indispensable for publicizing the challenge.
